Excerpt: Gertrude of Hohenburg (c. 1225 16 February 1281, Vienna) was the first Queen consort of Rudolph I of Germany. She was born to Burchard V, Count of Hohenberg (d. 1253) and his wife Mechtild of Tbingen. Her paternal grandparents were Burchard IV, Count of Hohenberg and his unnamed wife. Her maternal grandparents were Rudolph II, Count palatine and his wife, a daughter of Henry, Margrave of Ronsberg and Udilhild of Gammertingen. Burchard IV was a son of Burchard III, Count of Hohenberg. Burchard III was one of two sons of Burchard II, Count of Hohenberg. He was co-ruler with his brother Frederick, Count of Hohenberg. His brother had no known descendants and the two brothers consequently had a single successor. Burchard II was one of five known sons of Frederick I, Count of Zollern and his wife Udachild of Urach. Frederich I was the son of Burchard I, Count of Zollern. He was the founder of the so-called Burchardinger family line, male-line ancestors of the House of Hohenzollern.

They had nine children: Her husband was elected King of Germany in Frankfurt on 29 September 1273, largely due to the efforts of her cousin Frederick III, Burgrave of Nuremberg.

Rudolph remained a widower for three years and proceeded to marry Isabelle of Burgundy. ...More: http://booksllc.net/?id=10321497
